Macs fan control set to full blast and lifting the Mac above table for air circulation across bottom. I use M1 Max with qwen3.8 27b mlx. The gpu temp can reach easily to 95°C as fan doesn’t kick in automatically until 90°C. With Macs fan control at full blast and MBP off table, temp usually hover around 85°C.

Just curious, what is your ram and how many tokens per second do you get with that?

  I am getting like ~25 tps with M5 Max 64GB. Unsloth Desktop and Qwen 3.8 27B Q6 KXL

  RAM 32GB, tokens are less than 20, may be about 12-15. Main issue is context window, I have set to 64k but practically beyond 32k, too much swap and slow down.

Yikes isn’t 95 well above the danger zone for most components or have things changed? I remember crypto mining in the early 2010’s and making sure to stay under 85C on my GPU.

  Stuff runs so hot these days. I think one of the parameters pushed to keep Moores law from completely flattening was heat. My desktop regularly hits 95 just compiling code.

  I guess thermal throttling will inevitably kick in.
